Gorgeous 992B Charilaos! I wouldn't worry about the crack, that's just character (if you're keeping it for yourself).
Don't let anybody try to "restore" your dial, they are enamel, basically hand fired glass, over a copper base and cannot be re-enameled or repaired. Even the lettering is geletin transferred black glass dust, again hand fired, it can't be fired again. There are damn few out there who can do a decent job of these dials and lots who think they can but will only mess it up. Archer is right, there are ways to clean the cracks out a bit, but I'd leave well enough alone. The enamel won't degrade any more as long as its left alone...
Its a beautiful watch, get it serviced properly, run it regularly, wear it and enjoy it You'll find that a 992B in decent shape will perform as well as any COSC chronometre. These were working watches, meant to run inside 30 seconds a week for years in a dirty steam engines cab, that makes them better than a lot of fancy COSC dress watches in my books.
And here's you porn for tonight, the 992B's older brother.... the 992, this one from 1908.
Dials for these things turn up on ebay, its likely you could even find a suitable dial on a "parts" movement for less than the cost of having one fabricated. After all, Hamilton made 550,000 992Bs and, in their day, several companies were making very nice replacement dials for them as well.... so the stuff is out there.
I WISH I had not seen this thread.
I know these are old relics, and aren't worn nowdays.
But simply owning one and being able to look at the movement, and then the dial, and know precisely what the time is, and feel that nice big case with an engine beating inside.
🥰
The temptation is rising.
Maybe just ONE for my collection?
😗
I know that and thanks. But trusting my restaurateur I will "fabricate" one as the original instead buying something similar but not the real thing!
Puzzled by this - a genuine identical replacement Hamilton dial is not the real thing, but one fabricated from scratch is?
